PULSE-BASED BREAD CRUMB, COATING AND PRE-DUST ANALOG
PROCESS FOR MANUFACTURING THE SAME
FIELD
[0002] The invention relates to the field of bread crumb coatings and pre-dust
production, in
particular, to pulse-based bread crumb coating and pre-dust production.
BACKGROUND
[0003] In general bread crumb, coating, and pre-dust products are produced by
granulating or
pulverizing cracker or bread made of wheat flour by baking process.
Traditionally bread or
sheeted crackers are used as base ingredient and milled to produce granulated
crumbs and
powders in formulated systems. Wheat flour, salt, sugar, bicarbonate salts,
and vegetable oils are
added in formulation to improve the sheeting and baking processes and in
addition to enhance
taste and sensory properties.
[0004] Wheat flour and other grain-based flours are mixed with water and
variable ingredients
such as salt, sugar, yeast, bicarbonate salts, and vegetable oils. After the
mixing process, the
dough is hydrated with a water absorption range of 55-63%. The hydrated dough
is sheeted as
thin sheeted cracker dough and baked further at a range of 200-240 C. The
moisture is reduced
down to 12-14% and then baked cracker particles are milled into variable
granulations from
19343183v1

-2-
coarse (i.e. >500 micron), granular (i.e. 500-150 micron), and fine (i.e. <150
micron) particle
size.
[0005] Other methods such as extrusion can be also used to produce bread
crumbs, coating, and
pre-dust products. Wheat flour, corn flour, and other flours can be extruded
into hard crust
pellet, and are then milled into granulated crumb and powder products.
[0006] The wheat flour and other grain based flours are hydrated with water
and variable
ingredients such as salt, sugar, yeast, bicarbonate salts, and vegetable oils.
In an extruder, the
dough particles are hydrated with a water absorption range of 20-45%. The
hydrated dough is
extruded within a die at a temperature range from 120 C to 160 C. During
extrusion process,
the moisture is reduced down less than 12% and then extruded dried dough
particles were milled
into variable granulations from coarse (i.e. >500 micron), granular (i.e. 500-
150 micron), and
fine (i.e. <150 micron) particle size.
[0007] A process for the production of legume meal is described in W.O. Pub.
No. 2016/120234

DESCRIPTION OF THE DRAWINGS
[0016] While the invention is claimed in the concluding portions hereof,
example embodiments
are provided in the accompanying detailed description which may be best
understood in
conjunction with the accompanying diagrams where like parts in each of the
several diagrams are
labeled with like numbers, and where:
[0017] Figure 1 is a flowchart for producing a pulse-based bread crumb and the
like;
[0018] Figure 2 is a sensory evaluation comparison of a pulse flour to a heat
and moisture treated
pulse-based flour; and
[0019] Figures 3 to 6 are scanning electron micrograms of a pre-dust analog
under 300-micron,
100-micron, 20-micron, and 5-micron augmentations respectively.
DETAILED DESCRIPTION
[0020] There has been a recent increase in gluten-related disorders, such as
celiac disease, non-
celiac gluten sensitivity, wheat allergy, gluten ataxia, and dermatitis
herpetiformis. This has
been particularly problematic as some meats, etc. may be coated or bound with
gluten-based
products further limiting food selection for people with gluten-related
disorders. As knowledge
of these gluten-related disorders has increased, there has been a
corresponding increase in the
interest for gluten-free products. Example products may comprise gluten-free
bread crumbs,
powders, grains, and/or flakes.
[0021] Most conventional bread crumb coating contains some amount of gluten,
especially if it
.. is made from durum wheat flour. Pulse-based bread crumbs may be suitable
for gluten-free and
allergen-free applications that may be consumed by celiac patients, non-celiac
gluten allergy, and
gluten sensitive consumers. Pulse-based bread crumbs may be produced from
pulses, such as,
19343183v1
CA 3049198 2019-07-12
-7-
for example, peas, lentils, and faba beans. However, pulse flour and the pulse-
based bread
crumbs made therefrom may have an unappealing aftertaste for some consumers.
By using
processed pulse flours and specifically pulse flours processed using heat and
moisture treatment
as described herein, the process may produce improved taste, flavor,
appearance, and sensory
.. properties in comparison with the conventional bread crumb, powder, grain,
and/or flakes.
[0022] Low protein and medium protein pulse flours may produce a bread crumb,
coating,
and/or pre-dust analog by using a combination of steam, water, and/or heat in
a reactor as a
single allergen-free pulse-based ingredient as described further with
reference to FIG. 1. Pulse
flours may be produced by cleaning 100, dehulling, 102, fine milling/grinding
104, classification
106, heat and moisture treatment 108, and drying and milling processes 110 in
which the flow,
taste, and/or sensory properties of the flour may be enhanced as described
herein. For example,
bread crumbs, powders, grains, and/or flakes made according to the process of
FIG. 1 may
exhibit a reduced pulse flavor. Although the aspects described herein are
directed to peas, one or
more of these techniques may equally apply to other pulses, such as, but not
limited to, lentils,
faba beans, navy beans, pinto beans, and/or black beans (or any combination
thereof).
[0023] The cleaning process 100 may be applied to remove impurities from whole
peas so that
product cleanliness may be sustained. During the cleaning process 100,
impurities such as chaff,
other crops, stones, black-off colour kernels, damaged and/or broken seeds may
be removed.
[0024] Dehulling 102 may be applied to produce dehulled pulses (e.g. split
peas, split lentils, or
split faba beans) and to remove outer hulls so that outer fiber portion of the
peas may be removed
to remove the fiber and to increase the yield of protein and starch
separation. The outer hulls
may be removed in the dehulling process 102 using mechanical forces applied by
peelers. Since
19343183v1
CA 3049198 2019-07-12
-8-
the hulls adhere on a cotyledon on the outer part of a kernel, these forces
may help remove the
outer hulls from the whole kernel and separate cotyledon.
[0025] Fine milling 104 process may be applied to the split peas to produce a
raw pulse flour
with a particle size of below about 80 microns. The particle size of below
about 80 microns may
assist in classification 106 in order to separate a starch fraction from a
protein fraction. This
particle size may apply particularly to peas, lentils, faba beans, and/or
other low fat pulse crops.
The fine milling 104 process may use various systems such as, for example, a
pin mill, an ACM
mill, a turbo jet mill, and/or other fine grinding systems. The lower particle
size of the raw pulse
flour may assist separation of the protein and starch granule. At this fine
particle size, the
protein bodies may be removed from starch granules using such techniques as
described in at
least U.S. Pat. No. 1,861,248 to Stebbins or U.S. Pat. No. 3,089,595 to Alpine
Ag
Maschinenfabrik Und.
[0026] During classification 106, the raw pulse flour may be separated into a
limited protein
pulse fraction with a protein range of less than about 16% dry weight. The
medium protein pulse
fraction having over between about 20% to about 36% dry weight protein may
also be used
within blending systems in processing. The classification 106 may be performed
by a classifier
such as produced by Hosokawa Alpine Aktiengesellschaft, Sturtevant, etc.
[0027] Rather than classification 106, the limited protein pulse fraction may
comprise medium
(20-32%) level pulse flours (after fine milling 104) and may be blended with
pea, lentil, and/or
faba bean starch isolates (e.g. starch content >97% and protein <3%). Pulse
starch isolate may
be used as texturizing agents combined with medium protein pulse flours to
establish protein
levels at a range of 7-16%.
19343183v1
CA 3049198 2019-07-12
-9-
[0028] Heat and moisture treatment 108 may be applied to improve sensory and
flavor attributes
of the limited protein pulse flour fraction. The limited protein pulse flour
fraction may also be
agglomerated as part of the heat and moisture treatment 108. In some aspects,
the agglomeration
may be performed with a press mixer kneader operating in a range of about 80-
rpm to about 130-
rpm. The initial moisture content of the limited protein pulse flour fraction
before hydration may
be between about 4% to about 12% and may be measured prior to hydration in
order to
determine the amount of hydration required.
[0029] In some aspects, the limited protein pulse fraction may be hydrated at
a range from about
18% to about 55% by weight with water in a temperature range of about 30 C to
90 C at
.. atmospheric pressure to produce a hydrated pulse dough crumbles with a
temperature range of
about 70 C to about 85 C. The high temperature water and/or high pressure
steam may be added
and mixed to produce agglomerated pulse dough. The agglomerated dough may be
heated to a
temperature of between about 95 C to about 150 C to cook and dry the
agglomerated pulse
dough to a moisture content of less than about 12% moisture.
.. [0030] The hydration, heat, moisture treatment, and drying of the limited
protein pulse flour
fraction reduces levels of volatiles (e.g. hydrocarbons, alcohols, ketones,
and/or aldehydes) as
well as inactivates bitterness compounds (e.g. saponins, lectins and
phenolics) improving the
taste, flavour, and/or aroma. In particular, a sensory evaluation comparison
presented in FIG. 2
demonstrates the altered taste, flavor, and/or aroma characteristics between
the pulse flour and
the heat and moisture treated pulse flour. In particular, a pulse taste has
been reduced from a
strong taste (e.g. 8) to a more mild pulse taste (e.g. 3). The bitterness has
also been reduced by
half (e.g. from 6 to 3). During the heat and moisture treatment, a roasted
flavor may be
19343183v1
CA 3049198 2019-07-12
-10-
introduced (e.g. from 0 to 3) into the pulse flour, which may be preferable to
the pulse taste for a
consumer.
[0031] The agglomerated pulse dough pieces may be sifted and/or milled 110
into coarse (e.g.
over 2362 micron), granular (e.g. between 800 micron to 2362 micron), and fine
(e.g. less than
297 micron) as typical fractions. The agglomerated pulse dough may be milled
110 using a fine
grinding system such as, for example, an ACM mill, pin mill, turbo jet mill,
roller mill or any
fine grinding system, and passed through a standard US 100 mesh.
[0032] When the bread crumb, coating, pre-dust analog products described
herein are used;
allergen free, gluten free and single ingredient claims may be imparted. The
bread crumbs,
coating, and/or pre-dust analog may be applied to fried foods (e.g. breaded
chicken, chicken
nuggets, shrimp, fish, and/or fries). The resulting fried product may not be
too hard based on
internal sensory evaluation in oral sensation of coating and may maintain a
crispy sensation for
about 2-hours in fresh applications and 6-months in frozen applications. The
bread crumb may
also be mixed into sausage, meatballs, snack foods and/or bakery products and
may also be
mixed with cereal materials such as trail mixes, soups, and/or granola bars in
dairy food systems.
[0033] According to an aspect, the pulse-based bread crumb, coating, or pre-
dust may be applied
as a coating to a breaded food product at an inclusion rate from about 1% to
about 10% by
weight. The food product may comprise a fried chicken nugget, a fried shrimp,
a fried fish, a
potato product (e.g. French fries), a meat analogue, a texturized analogue, a
canned analogue,
vegetables, fruits, pickles, and a generic fried food product.
[0034] According to another aspect, the pulse-based bread crumb, coating, or
pre-dust may be
used as a binder in sausage, meatball, snack food, and bakery products at an
inclusion rate from
1% to 20%.
